Lets do a simple two step equation

For example, 

2x-8=12

Our main goal is to get the X value alone.

In order to do this, We will subtract 8 from both sides.

Our equation will now look like:

2x=20

In order to get the X alone here, We have to divide 2x by 2 in order to cancel out the 2 out. This means that since we divided by 2 on one side, we have to do it on the other. 

Our equation now looks like:

x=10

kari74 [83]

Answer:

1) 5/6 + 2/5 = 37/30   2) 1/6 - 1/10 = 1/15

Step-by-step explanation:

1) 5/6 + 2/5

  25+12/30

  = 37/30

2) 1/6 - 1/10

Choose all of the following angles that cannot
insens350 [35]

Answer:

Step-by-step explanation:

Answer:

Solution:

(i) 135°

No of sides = n

Each interior angle = 135°

(2n -4) x 90° /n = 135°

180n - 360° = 135n

180n - 135 = 360°

n = 8

Which is not a whole number

Hence, it is possible to have a regular polygon whose interiro angle is 135° .

(ii) 155°

No of sides = n

If two fair dice are rolled, what is the probability that the total showing is either even or less than five?
snow_tiger [21]

The Probability that the total showing is either even or less than five = 5/6

<h3>What is Probability?</h3>

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, where, broadly speaking, 0 represents the event's impossibility and 1 implies certainty.

<h3>According to the given data:</h3>

The example space for rolling two dice is:

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

36 events total.

Events that have a sum that is even or less than Five .

Total instances when the aggregate is even or less than Five equals 30.

P(sum is even or less than 5)

= (Total no of favorable event)/(Total no of event)

= 30/36

=5/6

probability that the total showing is either even or less than five = 5/6
